Dab tsi steel qib feem ntau siv rau UIC54 rail profile?
UAS 54 rail(tseem hu ua 54E1 rail lossis rail 54E1)yog tsim los siv siab -lub zog carbon steel thiab alloy steel qib tau teev tseg raws li UIC thiab EN cov qauv. Cov ntaub ntawv no yog tsim tshwj xeeb los daws cov log tsheb rov qab, kev sib cuag nrog kev ntxhov siab, thiab ntev - lub sij hawm qaug zog hauv kev siv tsheb ciav hlau.

Kev xaiv ntawm qib steel tsis yog random. Nws ncaj qha txiav txim siab hnav tsis kam, qaug zog lub neej, thiab tag nrho cov kav ntev ntawm UIC54 rail profile. NtawmGNEE RAIL, cov qib sib txawv yog tsim nyob rau hauv kev tswj dov thiab kev kho cua sov txheej txheem, kom ntseeg tau tias txhua txoj kev tsheb ciav hlau ua tau raws li qhov xav tauUIC54 rail specificationrau ntau yam kev ua haujlwm.
Main Steel Qib raucev 54e1
Cov qib steel feem ntau siv rau UIC54 rail profile yog txhais nyob rau hauv EN 13674-1 thiab dav saws nyob rau hauv thoob ntiaj teb railway tej yaam num. Cov no suav nrog R260, R300, R350HT, thiab hauv qee lub khw U71Mn.
Ua ntej muab piv rau lawv, nws yog ib qho tseem ceeb kom nkag siab tias cov qib no sib txawv feem ntau nyob rau hauv hardness, tensile lub zog, thiab hnav tsis kam, uas ncaj qha cuam tshuam rau txoj kev tsheb ciav hlau nyob rau hauv txawv loads.
- R260
Qhov no yog qib siv dav tshaj plaws rau UIC54 rail. Nws muab ib qho kev sib npaug ntawm lub zog thiab toughness. Nws yog haum rau cov qauv railway kab nrog nruab nrab qag loads thiab tsheb zaus. Nws qhov zoo dua yog kev ua haujlwm ruaj khov nrog tus nqi qis, ua rau nws muaj kev xaiv ntau hauv cov haujlwm loj -.

- R350HT (Tshav kub-Kho Rail Steel)
Qhov no yog qib siab - kev ua tau zoo nrog cov hardness siab dua. Cov txheej txheem kho cua sov txhim kho kev hnav tsis kam thiab qaug zog. Nws yog feem ntau siv hauv kev tsheb ciav hlau hnyav, siab - kab nrawm, thiab thaj chaw uas muaj kev tsheb ciav hlau hnyav xws li nkhaus thiab thaj chaw nres tsheb.
